Knowing the AM1 Platform that my AMD Athlon 5350 APU/ASUS AM1I-A motherboard run on more than likely does not support IOMMU like my desktop's 990FX does I figured it was a detection issue with the Linux kernel that ClearOS 6.5 utlizes.

Doing some research into the issue there are a couple adjustments to your GRUB configuration that may or may not resolve the issue. In my case adjusting my GRUB arguments upon boot to include iommu=soft resolved the issue. I'm hoping down the road with newer Linux kernels the detection (if that even is the issue) gets better, but for those running an AMD "Kabini" APU and ran into this issue you'll at least be able to boot into your Linux distribution without any issues.
